Quality time spent with the kids.
Suffer with mental health/ social anxiety which is exasperated by everyday situations.
Genuinely very scared of catching covid.
Hate work and love being furloughed.
Equally, some of the above have driven other people up the wall.
Being at home was certainly getting to me.
Yeah, I know somebody who would probably say overall benefit because he's got to be stay at home Dad to his newborn, and spend time he otherwise wouldn't get the chance to. He hates the lack of social, the worry etc, but he has had a chance he'd never normally get.
Ultimately the figures are small, so if you add in the people you say, and the ones who miss a commute...
It doesn't even mean they want it to continue, just on balance the experience has been positive.
(For clarity of the uncomprehending morons, none of the above are me)
Note it's younger people who are more likely to say positive, so job stresses probably account for that.
